  • Title: Genetics of heat-curability of killer virus of yeast.
    Author: Weinstein LA, Capaldo-Kimball F, Leibowitz MJ.
    Journal: Yeast; 1993 Apr; 9(4):411-8. PubMed ID: 7685559.
    Abstract:
    The cytoplasmically inherited M double-stranded (ds) RNA genome segment of killer virus of Saccharomyces cerevisiae is heat-curable in some yeast strains but not in others. Temperature sensitivity is conferred on both M1 and M2 dsRNA satellite virus segments by the L-A-HN allele of the killer helper virus genome, but not by the L-A-H allele. Both diploidy and mating type heterozygosity of the host cell are also correlated with increased virus curability.
